PIRSA:13110070  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Hofstadter’s Butterfly and interaction driven quantum Hall ferromagnetism in graphene
Speaker(s): Philip Kim
Abstract: Electrons moving in a periodic electric potential form Bloch energy bands where the mass of electrons are effectively changed. In a strong magnetic field, the cyclotron orbits of free electrons are quantized and Landau levels forms with a massive degeneracy within. In 1976, Hofstadter showed... read more

Unparticles and Fermi Arcs in the Cuprates
Speaker(s): Philip Phillips
Abstract: One of the open problems in strong correlation physics is whether or not Luttinger's theorem works for doped Mott insulators, particularly in the pseudo gap regime where the pole-like excitations form only a Fermi arc. I will begin this talk by using this theorem to count particles and show ... read more

Entanglement at strongly-interacting quantum critical points
Speaker(s): Roger Melko
Abstract: At a quantum critical point (QCP) in two or more spatial dimensions, leading-order contributions to the scaling of entanglement entropy typically follow the "area" law, while sub-leading behavior contains universal physics.  Different universal functions can be access through entang... read more

Topological Phases in Transition Metal Oxides
Speaker(s): Gregory Fiete
Abstract: Certain varieties of transition metal oxides possess both significant interactions and strong spin-orbit coupling. In this talk I will describe materials-motivated models that predict topological phases in heterostructured and bulk transition metal oxides. We find Z2 topological insulators, ... read more

PIRSA:13110074  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Quantum quenches & holography
Speaker(s): Robert Myers
Abstract: We employ holographic techniques to study quantum quenches at finite temperature, where the quenches involve varying the coupling of the boundary theory to a relevant operator with an arbitrary conformal dimension. The evolution of the system is studied by evaluating the expectation value of... read more

Majorana State Properties in Semiconductor and Oxide Superconducting Quantum Wires
Speaker(s): Allan MacDonald
Abstract: When proximity coupled to s-wave superconductors, quantum wires can support effective p-wave superconductivity under appropriate circumstances.  The p-wave state has  Majorana states at the wire ends which can store quantum information.  I will discuss some propertie... read more

Quantum and Classical Anomalies
Speaker(s): Michael Stone
Abstract: I will begin reviewing the Callan-Harvey mechanism of anomaly inflow with particular focus on topological edge states and show how the  inflow  picture naturally converts the non-covariant  "consistent" gauge anomaly  of Bardeen and Zumino to the more physic... read more

Twist Defects in Topological Systems with Anyonic Symmetries
Speaker(s): Jeffrey Teo
Abstract: Twist defects are point-like objects that support robust non-local storage of quantum information and non-abelian unitary operations. Unlike quantum deconfined anyonic excitations, they rely on symmetry rather than a non-abelian topological order. Zero energy Majorana bound states can arise ... read more
